Anti-Sea Clutter (STC) The Anti-Sea Clutter feature lowers receiver sensitivity at shorter ranges to reduce or eliminate echoes that reflect back at the antenna due to wave action close to the vessel. Caution Increasing STC may reduce or eliminate weak echoes, like small vessels. Use only the minimum amount needed, then check back periodically to see if the STC level may be decreased. To adjust Anti-Sea Clutter: 1. Anti-Rain Clutter (FTC) The Anti-Rain Clutter feature is used to reduce or eliminate massive numbers of small echoes that clutter the display during rain or snow storms.

Radar Echo Expansion The Radar Echo Expansion feature will make weak signals more visible on the display by lengthening radar echoes. To turn Radar Echo Expansion On/Off: 1. Press MENU, highlight RADAR ECHO EXPANSION and press ENT to turn it on (check) or turn it off (uncheck). Press EXIT. Tip: Remember, when Echo Expansion is on, all signals on the display will be enlarged, including clutter.
